Readers: "Prospect Transactions" updates you weekly on the most notable moves involving prospects in the Minor Leagues. All comings and goings of MLB.com's top prospects are included and are ordered by organization.

Notes: Skaggs made his Major League debut, allowing two runs and three hits over 6 2/3 innings in a 3-2 D-backs victory over Miami in the opener of the first home doubleheader in D-backs history. "It was phenomenal," he said. "I mean, the greatest feeling I've had so far in my life."

Notes: Turner allowed three runs and four hits in six innings in his first Major League start in the Miami organization, falling to Arizona and fellow rookie Skaggs. Miami manager Ozzie Guillen said Turner "was relaxed on the mound, very nice and loose. He was throwing a lot of strikes. He made one bad pitch but I like what I see."

Notes: MLB.com's fifth-ranked prospect made his Double-A debut on 8/21, pitching five scoreless innings. In 23 Florida State League starts -- where he met a familiar foe -- Taillon, 20, went 6-8 and fashioned a 3.82 ERA to go with a 98-to-37 strikeout-to-walk ratio. He re-joins fellow heralded right-hander Gerrit Cole in the Curve rotation. Taillon, the second overall pick in 2010, has been solid through 46 pro stats. His repertoire -- mid-90-mph fastball, hammer curveball and improved changeup -- gives him a chance to be spectacular at the higher levels.

Notes: MLB.com's 35th-ranked prospect left in the third inning of the Biscuits' 8/11 game after attempting to relay a throw to home plate. Lee had been struggling with the bat -- 3-for-his-last-30 at the plate -- but has played a pretty complete season in his first try at the Southern League. The 21-year-old shortstop has racked up 15 doubles, 10 triples, four homers and 37 steals in 116 games; he reached base safely in 46 straight, a streak that ended on 8/3.
